Turn, Stop, and Hazard Lights
The Turn, Stop, and Hazard Lights quit working overnight. All fuses are good. The 'Third' Stop light in rear window still works. Indicator lights in dash don't work either. Also Radio quit at the same time. Help?
Check the bulbs in the rear for being blown. Bad flasher or Bad turn signal switch, it controls turn and hazard. Indicator lights, the bulbs are probably blown in cluster. Sounds like you may have had a power surge.
See if alternator is charging too much.
